REFRIGERATOR.

Application mea're mary'aa, 1920. Serial No. 89,962.

My invention relates to improvements in i I refrigerators, and particularly to that type frigerator of this 7 kind, particularl of refrigerator wherein an ice chamber is positioned at one side of a refrigerating com partment, the refrigerating compartment extending under the ice chamber, and with an openwork, vertical partition between the refrigerating compartment and ice chamber,

and a passa eway through the bottom of the ice cham er to permit circulation from the refrigerating compartment through the ice chamber and 'back into the refrigerating compartment.- 7

I have, heretofore, in constructing this form of refrigerator, made the refrigerating compartment preferably of a one-piece construction, coated with-enamel by an enameling process requiring the application of intense heat, with the ice chamber-compartment of;

non-enameledconstruction. ;It is, in a. redesirable to have the interior coatedwith t is form of enamel, but there have been'maydifliculties to overcome 'in havin both the refrigerating compartmentand ice chamber coated with this form of enamel and at the same time be without the objectionable features:

of seams or cracks, into which the odors can p v so much of the structure?ae is-illustrated in pass and bring about a source of contamina-l tion. 1 v

An essential object of the present invention isthe securing of a construction in which both the refrigerating compartment and the ice holding compartment may be coated with this form of enamel before being placed in the refrigerator frame-work, and when placed to ether in the refrigerator frame- 7 work will e secured together in a'convenient and efiicient manner and without cracks, that will absorb anycontaminating odors, 1

A further object of my invention consists the refrigerating compartment against'sweat -of .improvements in the construction of the ice chamber compartmentjjthat will protect ing and leakage from therice'chamber comof air fromthe'ice to therefrigerating com,- partment,i with the maximum "rotectio'n of the contents ofthe'u refrigerating compart- I i l i .sAg-slclf'lf ia fi g al y' t fi m as 'cu a y por ion:and-maximum a i ly'th'er'efrom, the'right hand 'edgeQQ-jof said- These and other features ofniy-inventionf will appear more fully in the accom' filling description and drawings and will; """more,- I p shelf being spaced. inwardly from the adja particularly pointed out in the claiihs.

An important advantage of my invention lies in the structural independence of the ice chamber-and refrigerating compartment with cooperating means for joining together and sealing the two compartments when placed in position.
